With the new attribute rules are we able to populate attributes in one field with values from a feature that they intersect?

Example: I snap a point to a water pipe and want several attributes from that pipe to populate on in the point features attribute table. This was possible in attribute assistant and I am unable to figure out how to write the correct Arcade expression for it to work with attribute rules.

Arcade does not have that possibility yet (this would requite to store the pipe geometries and attributes in the expression itself and that would make it very slow). See also this discussion: Using Arcade Geometry functions in ArcGIS Online
